Summary Introduction
To determine:
Did the shot of epinephrine result in positive feedback mechanism occurring or negative feedback mechanism.
Concept introduction:
Carly was stung by a bee and was taken to the emergency room as her breathing and heart rate become more rapid. The doctors gave her a shot of epinephrine to reduce the allergic reactions which resulted in normal breathing and heart rate.

During a sympathetic nervous system response to an event, your heart rate increases, indicating the part of the heart responsible for controlling heart rate (the sinoatrial node) is innervated by sympathetic nerves. The SA node is also responsive to epinephrine,a hormone secreted by the adrenal medulla. Explain why the onset of the effect of the hormone is so much slower than the onset of the effect from sympathetic nerve stimulation and yet the effect of the hormone lasts much longer than the effect of nerve stimulation.
Halle Zingiber has been granted refugee status in this country. He has had to leave his wife and two children in Ethiopia. He is severely depressed and is receiving treatment with the tricyclic depressant, nortriptyline. No effects were reported when standard doses of the drug (25 mg tds) were used. His doctor increased the dose many-fold to 200 mg/day a dose, which is inducing effects. Can you explain Halle’s unusual response to therapy?
John is told that he has a hormone receptor
problem and his cells are not responsive to
hormone stimulation. Which of the following is a
possible reason for his problem?
Select one:
A. He has an ectopic tumor.
B. He has hypersensitivity to the hormone.
C. He has a receptor that has been
overstimulated.
D. He has too many receptors for the
hormone.
E. He has antibodies that block the function
of the hormone receptor.

- Which of these homeostatic mechanisms in the body are examplesof positive feedback, and which are examples of negative feedback?Why?a. The adrenal glands produce epinephrine in response to a hormone produced by the pituitary gland in times of stress; the pituitary gland senses the epinephrine in the blood and stopsproducing the hormone.b. As the bladder fills with urine, pressure sensors send messagesto the brain with increasing frequency, signaling that the bladdermust be emptied. The more the bladder fills, the more messagesare sent.c. When you drink an excess of water, specialized cells in yourbrain, as well as stretch receptors in your heart, detect theincrease in blood volume. Both signals are transmitted to thekidneys, which increase the production of urine.arrow_forwardThe hormone insulin enhances the transport of glucose (sugar) from the blood into most body cells. Its secretion is controlled by a negative-feedback system between the concentration of glucose in the blood and the insulin-secreting cells. Therefore, which of the following statements is correct? A decrease in blood glucose concentration stimulates insulin secretion, which in turn further towers blood glucose concentration. An increase in blood glucose concentration stimulates insulin secretion, which in turn lowers blood glucose concentration. A decrease in blood glucose concentration stimulates insulin secretion, which in turn increases blood glucose concentration. An increase in blood glucose concentration stimulates insulin secretion, which in turn further increases blood glucose concentration. None of the preceding is correct.arrow_forwardA hydrophilic peptide hormone is produced in the anterior pituitary gland located at the base of the brain.
